"Webincrease and reduce the sampling rate or frequency, usually by an integer factor. Increasing of a sampling rate requires that new values, not presented in the signal, be computed and inserted between the existing samples. The new value is estimated from a neighborhood of the samples of the original signal. " - Increase sample rate by integer factor
